With 50 mm, you choose a normal field of view on 35mm film for everyday life, travel, and people. Instead of turning a zoom ring, you determine the framing and spatial effect by your distance from the subject. The maximum aperture of f\/2.8 is the starting point for exposure and depth of field.\u003c\/p\u003e\n\n\u003ch3\u003eThe aperture design of the Exakta mount\u003c\/h3\u003e\n\n\u003cp\u003eThe manufacturer's brochure distinguishes the Tessar for earlier Exakta\/Exa cameras from the Praktica M42 version. For the Exakta mount, it specifies an automatic spring diaphragm. This distinction is practically important: You preselect the aperture, while the mechanical coupling belonging to the camera determines the shooting sequence. Therefore, an M42 description with a pin does not apply to this mount.\u003c\/p\u003e\n\n\u003ch3\u003eClose-up range in the model concept\u003c\/h3\u003e\n\n\u003cp\u003eFor the Tessar 50\/2.8 of the Exakta design, the manufacturer specifies a minimum focusing distance of 0.35 m and an M49×0.75 filter thread. This allows you to take a concrete distance into account when planning table shots or details. This value denotes the distance to the image plane and is neither a working distance in front of the lens nor a specification of the magnification scale.\u003c\/p\u003e\n\n\u003ch3\u003eSuitable camera and conscious workflow\u003c\/h3\u003e\n\n\u003cp\u003eThe offered mount is Exakta\/Exa. On a suitable SLR, you first look for the field of view and set the focus in the viewfinder. After that, you choose the working aperture for the subject. For digital use, a precisely matching adapter is required. The common Tessar name does not mean that mounts for Exakta, M42, or other historical cameras would be mechanically interchangeable.\u003c\/p\u003e\n\n\u003ch3\u003eCondition and limitations\u003c\/h3\u003e\n\n\u003cp\u003eCondition: well used.\u003c\/p\u003e\n\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Carl Zeiss Jena\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eModel:\u003c\/strong\u003e Tessar\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Lens\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLens mount:\u003c\/strong\u003e Exa\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFocusing:\u003c\/strong\u003e Manual\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFocal length:\u003c\/strong\u003e 50mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMaximum aperture:\u003c\/strong\u003e f\/2.8\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch3\u003eScope of delivery and image note\u003c\/h3\u003e\n\n\u003cp\u003eThe product mentioned in the title is delivered.\u003c\/p\u003e\n\n\u003cp\u003eFurther accessories are only included if they are expressly mentioned in the title as part of the offer.\u003c\/p\u003e\n\n\u003cp\u003eThe product images shown above serve as an example.
